Im wanting to build a Quad and I could use some advice. I already purchased a NAZA v2 W/ GPS now I am going to get the frame & Motors. I like the look of the TBS but the motors and ESC seem expensive. I want to get motors that will allow me to have fun. I am not going to video at first so I want to fly around, flip and roll... I want quality that will last and something I can eventually video with. I was looking at the TBS 900kv2, but does that seem expensive?
